I wasn't able to reproduce w/ 1.3.0 version on iPhone 4s w/ iOS 8.3 (cordova-ios 4.2.0). Here is the repro code I used: 
{noformat}
window.requestFileSystem(window.TEMPORARY,0, function(fs) {
    var fileTransfer = new FileTransfer();
    var uri = encodeURI("http://ovh.net/files/10Mio.dat");
    fs.root.getFile("test.dat", {create: true}, function(fileEntry) {
        fileTransfer.onprogress = function(progressEvent) {
            console.log("download percent");
            console.log(progressEvent.loaded/progressEvent.total*100);
        };
    
        fileTransfer.download(uri, fileEntry.nativeURL,
            function(entry) {
                console.log("download complete: " + entry.toURL());
            },
            function(error) {
                console.log(error);
            }
        );
    });
});
{noformat}

and here is the output:

> In CDVFileTransfer.m, download() method between line 447 to 462
> {noformat}
>     delegate.connection = [[NSURLConnection alloc] initWithRequest:req delegate:delegate startImmediately:NO];
>     if (self.queue == nil) {

>     [delegate.connection setDelegateQueue:self.queue];
>     @synchronized (activeTransfers) {
>         activeTransfers[delegate.objectId] = delegate;
>     }
>     // Downloads can take time
>     // sending this to a new thread calling the download_async method
>     dispatch_async(
>                    dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, (unsigned long)NULL),
>                    ^(void) { [delegate.connection start];}
>                    );
> {noformat}
> If I replaced it with the older version of the code, then it works.
> {noformat}
>     delegate.connection = [NSURLConnection connectionWithRequest:req delegate:delegate];
>     if (activeTransfers == nil) {
>         activeTransfers = [[NSMutableDictionary alloc] init];
>     }
>     [activeTransfers setObject:delegate forKey:delegate.objectId];
> {noformat}
> In summary, if we don't use GCD to start the NSURLConnection, it works.
